These 2 ASTER images were acquired on May 2, 2000 over the North Patagonia Ice Sheet near latitude 47 degrees south, longitude 73 degrees west. The left image covers an area of 30 x 20 km; the right image covers 36 x 30 km. The fals color composite displays vegetation in red. In the left image a number of glacial features: moraines, ice falls, crevasses, source snow field, toes, and a dark debris covered glacier. The right image dramatically shows a single large glacier, covered with crevasses. A semi-circular terminal moraine indicates that the glacier was once more extensive than at present.
